V8ZC1P Equivalent & Substitute Parts

Part Overview

The V8ZC1P is a Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc., designed for surge protection applications. This 8.5V rated disc varistor provides 100A surge current capacity in a 7mm through-hole package. The part is currently active in production with 964 units in stock. Substitute parts are identified when inventory constraints, supply chain disruptions, or manufacturing discontinuations necessitate alternative component selection while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The V8ZA1P is classified as a parametric equivalent to the V8ZC1P based on the following substitution criteria:

Electrical Parameters (Identical):

• Varistor voltage range: 6V (Min) to 11V (Max), 8.5V (Typical)
• Surge current capacity: 100A
• Maximum AC voltage: 4V
• Maximum DC voltage: 5.5V
• Energy rating: 0.4J
• Capacitance: 4190 pF @ 1 MHz
• Operating temperature: -55°C to 85°C

Mechanical Parameters (Identical):

• Mounting type: Through Hole
• Package: Disc 7mm
• Number of circuits: 1

Compliance & Status (Identical):

• RoHS3 Compliant
• REACH Unaffected
• Product Status: Active

The substitution is valid because all critical electrical performance parameters, mechanical form factors, and regulatory compliance certifications are identical between the two parts. The only difference is the internal series designation (ZC vs. ZA), which reflects different manufacturing batches or revisions within Littelfuse's product line while maintaining full functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both V8ZC1P and V8ZA1P are active production components from Littelfuse Inc. with identical electrical specifications and mechanical packaging. Selection between these parts should be based on:

Availability: The V8ZA1P offers higher inventory availability (2200 units) compared to the V8ZC1P (964 units), making it suitable for high-volume procurement or extended lead-time mitigation.

Compliance: Both parts meet ROHS3 and REACH requirements, ensuring regulatory compliance for applications in restricted substance environments.

Thermal Performance: Both parts operate across the identical temperature range (-55°C to 85°C), supporting equivalent thermal design margins.

Surge Protection: Both parts deliver 100A surge current capacity with 0.4J energy absorption, maintaining equivalent circuit protection performance.

Direct substitution is permissible in all applications where the V8ZC1P is specified, provided the through-hole mounting and 7mm disc package are compatible with the PCB design.

Frequently Asked Questions (FAQ)

Q: Can V8ZA1P be used as a direct replacement for V8ZC1P in existing designs?

A: Yes. The V8ZA1P is a direct parametric equivalent with identical electrical ratings (8.5V typical varistor voltage, 100A surge current), mechanical packaging (7mm disc, through-hole), and compliance certifications (ROHS3, REACH). No circuit redesign or re-qualification is required.

Q: What is the difference between the ZC and ZA series designations?

A: The series designation reflects internal manufacturing batch or revision coding within Littelfuse's product line. Both series maintain identical performance specifications and are functionally interchangeable.

Q: Are the mounting footprints identical?

A: Yes. Both parts use through-hole mounting with a 7mm disc package, ensuring identical PCB footprint compatibility.

Q: Do both parts have the same thermal operating range?

A: Yes. Both V8ZC1P and V8ZA1P operate across -55°C to 85°C, providing equivalent thermal performance in circuit applications.

Q: Which part should be selected for new designs?

A: Selection should prioritize component availability and supply chain stability. The V8ZA1P, with 2200 units in stock, offers superior availability for new production programs.

Q: Are there any differences in moisture sensitivity or handling requirements?

A: No. Both parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions and identical handling requirements.
